プラズモニック-フォトニックハイブリッド構造の熱ふく射特性

We investigated the radiation properties of a plasmonic-photonic microstructure using micro-particles. This diameters of the micro-particles are 5 mm. We measured and numerically calculated spectral normal absorptance of it. From measurement result and numerical calculation result shows absorptance peak at about 5 mm. we investigated the electric field distribution of the absorption peak by numerical calculation. From the calculation result of the electric field distribution, we confirmed that electric field is generated on the surface of gold and electric field is propagated along the periodic structure. Therefore absorption peak at about 5 mm is considered to be due to the periodic structure.
